The existing overpressure equipment has the technical problems that the control of overpressure pressure is inaccurate, the actual pressure is not controlled in place or is too large, and the phenomenon of sparking is easily caused by generally using an electric contact as a control device.

The range of the overpressure range is small, generally below 5 specifications, and the efficiency is low in batch production.

The number of interfaces is small, generally 40 or less interfaces, and the efficiency in mass production is low.

The prior equipment needs to screw the thread of the pressure gauge on the threaded interface of the equipment, so the operation is inconvenient, and semi-finished products are easy to damage during batch production.

The equipment volume is great, occupies area.

Manual timing or timing in a traditional relay contactor mode easily causes adjustment change during operation of workers, and quality control of an overpressure process of a product cannot be guaranteed.

The overpressure pressure value is calculated manually according to the full range of the pressure gauge, then the pressure control device of the pressure electric contact is adjusted manually, and then overpressure is started. The operation is complicated and easy to make mistakes.

The interface screw thread is single, and is restricted during the use, and is inconvenient during the change.

In summary, the existing pressure gauge overpressure equipment generally has the defects that the time on an overpressure process is manually kept or is simply controlled by a traditional relay contactor circuit, the stability is insufficient, the overpressure process time is insufficient or excessive easily, batch damage or too small pressure does not meet the production process requirement due to pressure overshoot is easily caused, multiple ranges of pressure, multiple interfaces and multiple specifications of rapid and convenient overpressure processes cannot be realized on one equipment, the production efficiency is low in unit time, and the existing pressure gauge overpressure equipment becomes a bottleneck process in pressure gauge production and the like.
